As stated before the large bore resonators look really bad being sooooo large so at K&D we use, install and sell the OEM size small bore stainless resonators. We typically do 2 1/4 inch stainless pipe. It takes some fiddling to get them to fit a larger bore exhaust pipe which we don't think is a big deal. You can slide 'em into the exhaust pipe and weld or clamp. These will quiet down the exhaust but won't diminish that nice bass that makes us smile! So if you don't want to scare the small children/pets or set off alarms in the neighborhood, I would definately install these. This price is for each.
